A New Zealand woman claims her grandmother is the secret daughter of former British prime minister Benjamin Disraeli. The claims are in a new book called 'Disraeli's Daughter'. Author Catherine Styles says her grandmother, Catherine Donovan, was very secretive about her chilhood, but told her she had been "farmed out" as a ward and spent some time as a child in London's high society. US Historian and Disraeli biographer Stanley Weintraub also believes the claim.
